What insert_picture does on Hwpx
AI agents use insert_picture to create or update resources in Hwpx, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Hwpx environment.
Why insert_picture is rated Medium
The tool creates new picture objects within a HWPX document and modifies its structure by adding binary data references. This is reversible modification (Write category) rather than destructive deletion. Severity is medium because inserting arbitrary pictures could bloat documents or introduce unwanted content, but the operation is not irreversible or financially consequential.
From the tool's definition Tool description indicates it "inserts picture object into body and saves together with BinData/manifest references" (insert_picture, 본문에 그림 객체를 삽입). This is a create/modify operation that adds content to a document.
Attacks that exploit this kind of access
The rule that runs insert_picture safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hwpx, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For insert_picture, this is the rule to start with:
insert_picture stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Hwpx, apply this rule, and every insert_picture call is checked against it from then on.
Questions about insert_picture
본문에 그림 객체를 삽입하고 BinData/manifest 참조를 함께 저장합니다. It is categorised as a Write tool in the Hwpx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Hwpx MCP server in PolicyLayer and add a rule for insert_picture: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Hwpx. Nothing to install.
insert_picture is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the insert_picture rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for insert_picture. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
insert_picture is provided by the Hwpx MCP server (airmang/hwpx-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
